Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Vehicle make and model identification using vision system
Full text linkCet article présente un système de reconnaissance du type (constructeur, modèle) de véhicules par vision. À partir d’une vue de face avant d’un véhicule, limitée à sa calandre, nous en construisons une représentation à base de points de contour orientés. La classification est réalisée essentiellement en se fondant sur des algorithmes de votes. L’utilisation d’algorithmes de votes permet au système d’être robuste aux données manquantes ou erronées de la représentation. Nous avons donc construit une fonction de discrimination qui combine 3 votes et une distance, et agit comme une mesure de similarité entre chaque modèle et l’image de véhicule testée. Deux stratégies de décision ont été testées. La première associe à une image de calandre avant du véhicule, le modèle qui a obtenu la valeur la plus importante en sortie de la fonction. Une seconde stratégie regroupe toutes les sorties en un vecteur. La décision est alors prise via un algorithme de plus proche voisin dans un espace dit de votes. Avec la première stratégie, un taux de reconnaissance de 93 % est obtenu sur une base d’images prises en conditions réelles composée de 20 classes de type de véhicules. De plus, une caractérisation et une analyse du fonctionnement du système vis-à-vis de ses différents paramètres est proposée. Cependant ce taux chute à 80 % lorsque le nombre de modèles passe à 50 classes. Pour le même nombre de classes, la seconde stratégie permet d’obtenir un taux supérieur à 90 %.Many vision based Intelligent Transport Systems are dedicated to detect, track or recognize vehicles in image sequences. Three main applications can be distinguished. Firstly, embedded cameras allow to detect obstacles and to compute distances from the equiped vehicle. Secondly, road monitoring measures traffic flow, notifies the health services in case of an accident or informes the police in case of a driving fault. Finally, Vehicle based access control systems for buildings or outdoor sites have to authentify incoming (or outcoming) cars. Rather than these two systems, the third one uses often only the recognition of a small part of vehicle: the license plate. It is enough to identify a vehicle, but in practice the vision based number plate recognition system can provide a wrong information, due to a poor image quality or a fake plate. Combining such systems with others process dedicated to identify vehicle type (brand and model) the authentication can be increased in robustness. This paper adresses the identification problem of a vehicle type from a vehicle greyscale frontal image: the input of the system is an unknown vehicle class, that the system has to determine from a data base. This multiclass recognition system is developed using the oriented-contour pixels to represent each vehicle class. The system analyses a vehicle frontal view identifying the instance as the most similar model class in the data base. The classification is based on voting process and a Euclidean edge distance. The algorithm have to deal with partial occlusions. Tollgates hide a part of the vehicle and making inadequate the appearance-based methods. In spite of tollgate presence, our system doesn’t have to change the training base or apply time-consuming reconstruction process.Fil: Clady, Xavier. Université Pierre et Marie Curie-Paris 6.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
